Glycolic acid esters and amides of bis(p-disubstitutedaminophenyl)carbinol

Abstract

Glyolic acid esters and amides of bis(p-disubstitutedaminophenyl)carbinols are disclosed as color formers for use in transfer sets.

What is claimed is: 
     
       1. A compound represented by the Formula (1): ##STR29## wherein R 1  and R 2 , which may be the same or different, represent hydrogen, alkyl containing from about 1 to 4 carbon atoms, which may be substituted by a nitrile, hydroxyl or a 2 to 8 carbon alkoxy group, phenyl or alkyl (C 1  -C 4 ) substituted phenyl, benzyl or alkyl (C 1  -C 4 ) substituted benzyl; R 3  represents hydrogen or alkyl containing about 1 to 5 carbon atoms; and Z represents an ester or amide group represented by Formula (2) and (3), respectively: ##STR30## wherein R 4  represents hydrogen, alkyl containing about 1 to 5 carbon atoms, phenyl or alkyl (C 1  -C 4 ) substituted phenyl, or benzyl or alkyl (C 1  -C 4 ) substituted benzyl; R 5  represents alkyl containing about 1 to 12 carbon atoms, either in a straight or branched chain, which chain may be interrupted by a hetero atom, phenyl or alkyl (C 1  -C 4 ) substituted phenyl, or benzyl or alkyl (C 1  -C 4 ) substituted benzyl; R 6  and R 7 , which may be the same or different, represent hydrogen, alkyl containing about 1 to 12 carbon atoms in either a straight or branched chain, which chain may be interrupted by a hetero atom, phenyl or alkyl (C 1  -C 4 ) substituted phenyl, benzyl, or alkyl (C 1  -C 4 ) substituted benzyl, or wherein R 6  and R 7 , taken together with the nitrogen atom to which they are attached, combine to form a morpholine ring. 
     
     
       2. The compound of claim 1 wherein R 1  and R 2  are both methyl or ethyl groups. 
     
     
       3. The compound of claim 1 wherein R 1  and R 2  are ethyl and R 4  is hydrogen or phenyl. 
     
     
       4. The compound bis(p-diethylaminophenyl)methoxy acetic acid, benzyl ester. 
     
     
       5. The compound 4,4'-bis(N,N-diethylamino)benzhydrol, ethyl glycolate. 
     
     
       6. The compound bis(p-diethylaminophenyl)methoxy acetanilide.
